ENV File Parser
Paste the contents of a .env file and inspect every variable in a clean table — with type detection, empty-value and duplicate-key checks, malformed-line detection, and warnings on sensitive secrets. Everything runs locally in your browser.
How to use
- Paste the contents of your
.envfile into the box, or click "Load sample" to try it with example data. - Click "Parse" to see every variable as a row: key, value, detected type and a status badge.
- Read the warning panel at the top for duplicate keys, malformed lines, empty values and sensitive keys.
- Use "Copy as JSON" or "Copy as table" to reuse the parsed result in documentation or chats.
Note: comment lines starting with # are skipped. An export KEY=value prefix is handled. Only the first equals sign splits key from value, so values may contain equals signs.
Tips
- A duplicate key means the last occurrence wins in most parsers — remove the earlier one to avoid confusion.
- An empty value like DB_PASSWORD= is a real setting in most frameworks; the parser marks it so you notice it.
- If a key has an unexpected type, check for stray quotes or spaces around the value.
Frequently Asked Questions (FAQ)
What is an env file?
An env file, usually named .env, stores application configuration as KEY=value pairs, for example database credentials, API keys and feature flags, so the code can read them without hardcoding secrets.
What types does this parser detect?
Every value is classified as string, number, boolean or URL, and empty values are marked empty so missing configuration stands out.
How does the parser find sensitive keys?
Any key containing PASSWORD, SECRET, TOKEN, API_KEY, or PRIVATE is flagged with a warning badge, because such values are secrets that must never be committed to version control.
What counts as a malformed line?
A line that is not a comment and does not contain an equals sign is malformed, for example a key written without a value assignment. The parser lists these separately so you can fix them.
Does my .env content leave my browser?
No. All parsing happens locally in JavaScript on your device; nothing is uploaded, stored or sent to any server.
